party exp distribution

[Shahar6]

When in a party and killing a mob, one of the party members (the one who dealt the most damage) gets the maximum exp and the others get the minimum exp (regardless of their damage), for example, 6 characters are in a party and two attack a zakum arm, lets say it gives 100 exp, one of them dealt 51% of the damage and another 49% the rest didn't participate but are within the level interval to leech, the one who dealt 51% will get 20+80/6 exp and his friends 80/6 exp each, instead it should be, the one who hit 51% gets 51%*20 +80/6, his friend 49%*20 +80/6 and the other 4 80/6

example takes into account the default values:
EXP_SPLIT_MVP_MOD: 0.2
EXP_SPLIT_COMMON_MOD: 0.8
PARTY_BONUS_EXP_RATE: 1.0
